Energy Saving Lux LoÉ Glass

There are many LoÉ glass types available to suit virtually any climate; Lux Windows uses a superior product most beneficial when considering energy efficiency for Canadian weather. LoÉ is a unique, microscopically thin coating (not affecting clarity) containing transparent layers of metal and metal oxides. This metal coating works in tandem with an argon gas enhanced airspace, greatly reducing the sun's hot rays from entering the home in the summer, and also traps interior climate conditions reducing energy costs of both heating and air conditioning.

Each and every Lux window and door is available with LoÉ glass. LoÉ also significantly resists damaging ultraviolet rays, protecting your curtains, furniture and flooring from fading.
